it is getting difficult to use office washroom,as it is used by both Hindus and Muslims. while washing hands in sink, the water touches the sink and then the same water drops comes on clothes or hands. or shirt touches the sink and it gets wet. am I najis in this case? because while washing my hands, cheete ud rahe hai, fir Galti se shirt sink ko lag Gaya and wet hogaya. is it najis? because sink is used by both Hindu and Muslim

islam is a not a difficult religon, we r making it difficult, in our shariat there is a usool or qaedah,,every thing is paak until u sure it become najis, jab tak aapko yaqeen yani 100% sure na hon ki ye hindu se touch hua pani hai tab tak wo paak hai
